The graph of the function f(x) = –(x + 3)(x – 1) is shown below.

on a coordinate plane, a parabola opens down. it goes through (negative 3, 0), has a vertex at (negative 1, 4), and goes through (1, 0).

which statement about the function is true?

the function is positive for all real values of x where

x < –1.

the function is negative for all real values of x where

x < –3 and where x > 1.

the function is positive for all real values of x where

x > 0.

the function is negative for all real values of x where

x < –3 or x > –1.

step-by-step explanation:

72 is the answer to this problem

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.

so, converting firstly the mixed fractions to improper fractions and then "adding".
